Most concrete used for construction is a combination of concrete and reinforcement that is called reinforced concrete. Reinforcement for concrete is provided by embedding deformed steel bars or welded wire fabric within freshly made concrete at the time of casting. The purpose of reinforcement is to provide additional strength for concrete where it is needed.
